ENGLISH ABSTRACT: In this study a new type of gearless, direct-drive wind generator, which can be connected directly to the grid,
is proposed. The working characteristics of this generator are based upon the principles ...

ENGLISH ABSTRACT: The world is increasingly being faced with the challenge of effectively exploiting
available renewable energy resources, not only to meet an ever growing energy demand, but also
to preserve the available ...

ENGLISH ABSTRACT: This document details the design process of a 97 kW microhydro system for Roman Bay Sea Farm in Gansbaai in the Western Cape Province of South Africa.
It contains a literature study of microhydro power, ...

ENGLISH: The design, construction and testing of a passive thermal system, a roof solar
chimney, for a loft is considered. Unlike conventional solar chimneys the solar
collector is constructed from corrugated iron roof ...

Globally, transport and its associated ills are creating urban landscapes that can best
be described as unhealthy, unfriendly and unsustainable. The unsustainable nature of
current transportation practices are most keenly ...

This report covers the development of a biofuels engine testing facility at Stellenbosch
University. The motivation for the project was three fold: a) a desire to establish biofuels
and engine testing know-how; b) to ...

ENGLISH ABSTRACT: This thesis investigates the case of the Cape Town Central City Provincial Government
Revitalisation Initiative (CCPGRI) as a means to further understanding of socio-technical
transitions. The departure ...

ENGLISH ABSTRACT: Renewable energy technology has received much attention over recent years. The depletion of known fossil fuel reserves and the volatility of international fuel prices require that society looks beyond the ...

The aerodynamic performance of an existing wind turbine blade optimised for low wind speed
conditions is investigated. The aerodynamic characteristics of four span locations are determined from
surface pressure measurements ...

ENGLISH ABSTRACT: Recently, improved technologies have been developed for the biobutanol fermentation
process: higher butanol concentrations and productivities are achieved during
fermentation, and separation and ...

ENGLISH ABSTRACT: South Africa is facing an energy crisis on two levels; the existing capacity to supply electricity is
unable to support future growth in demand, and the electricity being produced comes mostly from
coal-fired ...

This paper describes a MEng thesis project for a MEng in
Renewable Energy Systems program at the Centre for Renewable
Energy Studies at the University of Stellenbosch, South Africa. The
aim of this paper was to offer ...

ENGLISH ABSTRACT: Knowledge of the magnetic fields in the domain of electrical machines is required in order
to model machines accurately. It is difficult to solve these fields analytically because of
the complex geometries ...

This thesis is an investigation of the wave power resource on the South African coast,
focusing on the spatial distribution of wave power of the coastal region exposed to the
highest wave power. The study’s main objective ...

ENGLISH ABSTRACT: The dissertation builds on previous research (Pretorius, 2004) and investigates the optimization and control of a large-scale solar chimney power plant. Performance results are based on a reference location ...

This study evaluates the performance characteristics of a power plant incorporating a steam turbine and a direct air-cooled dry/wet condenser operating at different ambient temperatures. The proposed cooling system uses ...

ENGLISH ABSTRACT: Solar energy is by far the greatest energy resource available to generate power.
One of the difficulties of using solar energy is that it is not available 24 hours per
day - some form of storage is ...

ENGLISH ABSTRACT: This project investigated the feasibility of incorporating photovoltaic cells into
plastic roof tiles using injection moulding. Such tiles have the potential to provide
robust and distributed electricity ...
